What is a proper fleet to counter that tengu squad? Here's a quick breakdown of why its such a mean fleet- A typical T2 PL tengu:

Damage Effective to 117km

550dps

2200 damage alpha

smallish sig radius (205 m)

130k ehp according to eft (at least 90k in game)

650 m/s

35 sensor strength

All of this without fleet bonuses(tengu does have the subsystem for it remember), and how many are running faction and deadspace mods? probably a few...
So how would you go against this fleet?
A battleship fleet?

Maybe. Do you have enough T3 armor tackles(loki's and proteus's? or are you just going to suicide cruisers for tackle? Battleships cant keep up with tengu's going 550-600 m/s with afterburners, even if you managed a warp in at 0, you wouldn't hold them down long. Once they're 70km off of you your battleships are doing basically no damage(with short range setups), their logi is positioned at the other side of the fight, and they're sitting there pounding your tackle. You're fucked.

An armor hac gang? Yeah, fair damage against tengu's, but less buffer, they're still doing full damage to your armor hacs with good skills, your logis probably aren't going to keep up with the damage. They don't have to fight at <30km like you do either, they can just burn off of you at 70km all the while pounding your logi with missiles. They're faster, so they dictate the terms of the engagement. Yeah, you might tackle one or two, but you can bet whatever tackle is on the field is going down before your logistics even lock them.

Drake fleet? Please... maybe with 300 of them, even then they're going to be popping one every 5 seconds, 40 tengu's with 2200 damage volleys is about 88000 damage... every 4 seconds. Can you even keep a tackle with a drake? Probably not.

Jamming? Who are you gonna jam? their logi? Even if you manage to they have 130k ehp, 162 dps passive regen, and they're going to kill one of your jamming boats every 5 seconds, you better bring a lot.
Damping? Probably not your best bet, but it would have to be combined with a short range ahac or bs fleet. 1 damp on each tenu would limit their effective range to under 70km, so you need at least 2 per tenu. How are you even going to coordinate 2 damps per tengu in a big fleet though? Plus they can still always burn in close pop one or two of your ewar or logi's and burn off.

Even twice their numbers isn't really going to make a dent in a tengu/scimitar fleet. Start bringing out 3 times their numbers, over 120 pilots or so, and you start having problems with getting dps down, range, and logistics becomes a nightmare, unless whoever is their primary is already locked, its already down by the time you broadcast. Drop a super carrier or two? Yeah that turns out well againt PL...

Long answer: its a function of the tracking speed, signature radius of the target you're shooting, and orbit speed/optimal of the drone shooting it. If you're hitting a small target, with a small signature radius, with large drones with poor tracking, painting the target and making it a "bigger" will increase your chances of hitting it. Using warriors on a target painted battleship will almost certainly make no difference, whereas using ogres on a frigate it will definitely help.

In our defense, we had someone watching dscan, he just failed horribly...
That said, probes weren't needed to find us, so the only thing he could have seen was the proteus decloak the instant it comes through the wh, or the heretic while in warp. In the latter case we could have saved the carrier and tengu's possibly, both dreads were mid siege cycle. We definitely should have had probes going to look for new wormholes but didn't (didn't have any spare probing alts online). We could keep alts in nearby wormholes to watch for this sort of thing, but dont have the man power(or the monitors). I suspect they came from the static c2 anyway. I called one of the bhal's primary on land but the carrier was completely capped in like 20 seconds. Once the huggin died the dreads couldn't put any damage on field at all, not that there was any way we were ever going to win that fight anyway. We had a contingency plan in place for this sort of thing, but I knew the tech3 bling fleet would take us down if we were ever dropped on with it (worst case scenario). We'll be running t2 fits from here on out for the blingus, the faction shit wasn't really ever needed. Out of curiosity, how long had you guys been watching? We had done 1 other full capital escalation before this one. The archon didn't warp in because it was pilot-less sitting in the pos. Also putting -A- on the title is a bit misleading, there was only 1 -A- Alt in the whole thing. In the end its a calculated risk, we run them like this in less than hour with 4 pilots, narwals aren't stupid, they set this up well and caught us, its what they do. Tl;dr: 250m/hr per pilot, shit happens.

I'm no mountain climber, but if you're not sure how serious you are I think you've already disqualified yourself for doing it.

Assuming you were motivated, and you really wanted to do it you'd need:

fyi, they reject prepaid debit cards, if there is such a thing as a "prepaid credit card" they put a hold on the account for the cost of the dvd, after the rental is done they release the hold and charge you the rental fee.
